STEREOSCOPE.

. T (ZZZ whom/it may concern.

Be it known that I, HENRY E. RICHMO D,

" of Westwood, in the county of Bergen and 6 State of, New Jersey, haveinvented certain :new and useful Improvements in Stereoscopes, of whichthe following; is a full, clear, and exact description, such as willenable others skilled in the art to which 1t appertains tomake and usethe same.

This invention relates to improvements in hand stereoscopes, commonlycalled in the art scopes. i

Scopes as heretofore constructed generally consist of a Wooden shaft, ahood con nected to one end ofthe shaft, a lens frame within, the hood, aseptum connected'to the hood between-the lenses and extendinglongitudinally of the shaft, a picture holder 1 slidedly mounted on. theshaft for focusing the picture and a handle pivoted to fold againstthebottom of the hood or shaft.-

Scopes' so constructed are ibulky. Frej quently the septum does notdivide thepicture perfectly, so that in focusing a part of one of theviews extends over the other, or.

one of the views is cut off so that all of it willnot be observedthrough, the lenses and therefore a perfect picture is not in view ofthe user of the scope.

One of the objects of my invention is to provide a scope with the shaftand picture holder so constructed that they can be fold edinto the hoodto make a compact scope,

for packing or: storing.

[Another object is to provide. means by which the lens frame may bemoved backward and forward or adjustedwithin the hood so thatthedistance of'the lens from the eye may be adjusted as the holder is movedtoward or from the hood and the picv ture brought in perfect focus. The'con-. structionis such thattheseptum'is also dis 1 pensed with. 1 l

, Other objects will appearfrom the'hereinafter description. 1 1 v Theinvention, willv be fully understood from the following descriptiontaken in connection with the accompanying drawing.

.-.Referringto the drawing, in which the same reference characterindicates the same part in the several views: Figure 1 is a side viewofthe invention with the shaft and handlein their extended positions andthe hood sectioned on line 1 of Fig. 3 Fig. 2, is

' outer endsj65 and 66 of Specification of Letters Patent. Pategntefl13, 19,1915.

.- Application filed May 14, 1914. Serial 0. 838,434.

a, view similar to that of Fig. 1 with the shaft and picture holdercollapsed into the hood and the han'dlefolded against the bottom of thehood. Fig. 3, is a top planview of the-invention with: the hoodsectioned on line 30f Fig. 1. Fig. 4, is a rear view of the inventionwiththehandle extended.

The part marked 20 on the drawing rep-' I resents the hood whichconsists of the ablelongitudinallythereof. Pivoted to the base of thehood are the arms 35 and 86, the hood being depressed at 37 and 38 toreceive the arms so thatt-hey willnot extend above the upper surface ofthe base. Pivot ed to the free-ends of these arms are the ends 40 and41. of the'lazy tongs 42 which form in the'speciiic constructionhereshown, the extensible shaft. The lens frame is se-' curedtothe, shaft at43.

44 is a picture holderwhich consists of the cross member 45 made ofsheet metal, the upper edges 46 and 47 of which are overturned to formways or guides into which slide the plates 48 and 49, the outer parts 51and 52 of which are upturned and the ends 53 and 54 are outturned' andthese parts of theslides are slotted at 55 and 56 to receive the edgesofthepicture A. To limit.:the-;out ward.movement of the plates 48'and 49the same are providedwith longitudinal slots 57 and 58' through whichextend the rivets or pins 60 and 61. These rivets pivot to the undersideof the picture holder 44, the arms 62 and 63, to which the the lazytongs are pivoted.' x

'67, is a stop which consists ofa plate se- 7 curedto the under side ofthe picture holder 44 below the arms 62 and 63. This plate isprovided-with a longitudinal slot 68 into which projects one, of thepins 69 connecting members of the lazy tongs. When this pin takesagainst the inner. end of the slot, the outward movement of theextensible shaft or lazy tongs is limited. To receive the. headsofthe'pins or'rivets 43, 69 and 7 0 pivotin the c oss members of thelazy tongs together so that the members of. the lazy tongs Will lieflush againstthe top surface thereto or cars 73 may be secured byriveting or elding to the downwardly strucli portion 71 and the'handlepivoted to the ears as shown. r

' When the scope is to my invention, the picture holder, and shaftmay befolded to fit within the hood as shown in'IfigQ and the handle foldedagainst the baseio'f the hood so that the scope is compact and takes uplittle room'- for'storing. When the scope is to be used,

the shaft is extended and the slides orplates 48 and are 7 drawn ,outfto receive the picture A asshoW'n in Figs; 1 and 2.1 The picture holdercan be moved toward or away from the hood, ivhich movement adjusts the,lens frame longitudinally Within the hood and brings the lenses closerto or farther away from the'eye of the observer until. the picture isadj usted-to 'shoW a sharp 7 and distinct-view, By this construction thec so septum is dispensed with. It is apparent that changes may I haveshown anddescribed What I consider'to'be' at the; present 7 time, thebest embodiment of my invention;

. Otherforms of shaft may be used forkzonnecting and adjusting the lensframe and" the picture holderjand I'may constri'ict the part so' thatthe lens frame "and picture holder need notbe moved ora'djusted onerelative to the other simultaneously.

What I claim as new and desire toobtain by Letters Patent, is; 1. In astereoscope, a hood, a lens frame insaid hood and means for adjustingthe frame longitudinallyvof the'hood.
